FUN14 domain containing 1 (FUNDC1) is an important molecule in receptor-dependent mitophagy. However, the roles of FUNDC1 in human cancer biology remain unknown. The aim of this study was to explore the expression and roles of FUNDC1 in cervical cancer. Immunohistochemistry and Western blotting were applied to detect the expression of FUNDC1, and small-hairpin RNA was applied to inhibit the expression of endogenous FUNDC1 in cervical cancer cells. MTT assays and Flow cytometric analysis were applied to examine cell proliferation and apoptosis...

PURPOSE: To provide evidence-based, resource-stratified global recommendations to clinicians and policymakers on the management and palliative care of women diagnosed with invasive cervical cancer. METHODS: ASCO convened a multidisciplinary, multinational panel of cancer control, medical and radiation oncology, health economic, obstetric and gynecologic, and palliative care experts to produce recommendations reflecting resource-tiered settings. A systematic review of literature from 1966 to 2015 failed to yield sufficiently strong quality evidence to support basic- and limited-resource setting recommendations; a formal consensus-based process was used to develop recommendations...

Metastasis to the breast from an extra-mammary malignancy has been documented in literature, however cervical cancer metastasis to the breast is very rare. Thirty-eight cases of metastatic deposit to the breast from cervical cancer have been reported in literature. Though most patients present with a breast lump, it is very difficult to clinically distinguish a primary breast malignancy from a metastatic deposit. Histopathology of the tissue, aided with immune-histochemical staining pattern provides a definitive diagnosis...

BACKGROUND: Radiochemotherapy in cervical cancer was implemented to clinical practice based on five randomized clinical trials, published at the end of 20th century, which showed improvement in total and symptomless survivals by about 10 to 18 %. The increase of therapeutic index of such treatment can take place only at the advantage of the efficiency over the increase of its toxicity. Thus, it is necessary to monitor treatment reaction during radiochemotherapy. OBJECTIVES: The aim of this study is to assess the acute post-radiation reaction during radiochemotherapy for cervical cancer and the analysis of the reasons of the unplanned course of combined treatment...

Hypoxic conditions are common in solid tumors and have a significant effect on tumor progression, therapeutic and prognosis. Long noncoding RNAs (lncRNAs) are longer than 200 nucleotides and cannot be translated into proteins, which play important roles in some diseases including cancer. Although previous analysis have showed that long intergenic non-coding RNA (lincRNA)-p21 is hypoxia-responsive and functions as a new regulator of cell cycle, apoptosis and warburg effect in cervical cancer, its biological roles in hypoxic hepatoma and glioma are unknown...

Nowadays, total laryngectomy is primarily performed for advanced laryngeal cancers with involvement of the laryngeal skeleton and/or extending outside the larynx, hypo- or oropharynx. Another field of application is represented by salvage surgery following chemo-radiation therapy failure. In both these situations, laryngectomy is achieved by therapeutic or elective neck dissection(1-2) . This procedure is carried out by adopting an open trans cervical approach.

Homeobox containing 1 (HMBOX1) modulates telomere length in various types of tumor cells by binding to double‑stranded telomeric DNA. There is a negative correlation between telomere length and radiosensitivity in tumor cells. In the present study, we aimed to investigate the relationship among HMBOX1, telomere and radiosensitivity in cervical cancer cells. Lentivirus-based shRNAs were used to establish stable transfected cell lines in which protein and mRNA levels of HMBOX1 were notably decreased. Knockdown of HMBOX1 increased the radiosensitivity of HeLa and C33A cells...

RAD51 is one of the pivotal enzymes for DNA double-strand break (DSB) repair by the homologous recombination (HR) pathway, which implies it as a promising and novel target for cancer therapy. Recent findings have indicated RAD51 protein is overexpressed in a variety of tumors. The high-expression of RAD51 is related to poor prognosis. RAD51 is involved in the repair of DNA damage and the generation of genetic diversity by an evolutionarily conserved mechanism. However, the exact mechanism of Rad51 in the progression of cervical cancer remains unclear...

Neoadjuvant (or induction) chemotherapy can be used for cervical cancer patients with locally advanced disease; this treatment is followed by radical surgery and/or radiation therapy. Cisplatin is considered to be the most active platinum agent drug for this cancer, with a response rate of 20%. In order to understand how the cisplatin treatment affects the stress response, in this work, we performed an exploratory study to analyze a number of stress proteins before and after cisplatin neoadjuvant chemotherapy...
